0.系统版本

0.1 查看系统版本

 [root@localhost ~]# uname -a
 Linux localhost.localdomain -.el7.x86_64 # SMP Tue Nov  :: UTC  x86_64 x86_64 x86_64 GNU/Linux

1.安装requests

1.1 软件下载

 [root@localhost ~]# wget \
 https://pypi.python.org/packages/b0/e1/eab4fc3752e3d240468a8c0b284607899d2fbfb236a56b7377a329aa8d09/requests-2.18.4.tar.gz#md5=081412b2ef79bdc48229891af13f4d82

1.2 解压

 [root@localhost ~]# .tar.gz 

1.3安装requests

 [root@localhost ~]# cd requests-
 [root@localhost requests-]# python setup.py install

1.4 安装报错

 [root@1e supervisor-3.0]# python setup.py install
 Traceback (most recent call last):
   File , in <module>
     from setuptools import setup, find_packages
 ImportError: No module named setuptools  

原因是没有找到setuptools包，再次安装这个包

下载setuptools :

 [root@localhost requests-]#wget \
 https://pypi.python.org/packages/a4/c8/9a7a47f683d54d83f648d37c3e180317f80dc126a304c45dc6663246233a/setuptools-36.5.0.zip#md5=704f500dd55f4bd0be905444f3ba892c

利用unzip进行解压

 [root@localhost requests-]# .zip 

如果提示没有找到unzip命令，则利用yum安装即可

 [root@localhost requests-]# yum install zip unzip 

解压完成后即可进行安装

 [root@localhost requests-]# cd setuptools-
 [root@localhost setuptools-]# python setup.py install

安装完成后即可进行安装requests

 [root@localhost setuptools-]# cd ../
 [root@localhost requests-]# python setup.py install

安装完成检验，进入python交互式界面进行导入包即可

 [root@localhost requests-]# python
 Python  (default, Nov   , ::)
 [GCC   (Red Hat -)] on linux2

 >>> import requests
 >>> 

2.安装requests

2.1 软件下载

 [root@localhost ~]# wget \
 https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip#md5=654f75b302db6ed8dc5a898c625e030c

2.2 解压并且安装

 [root@localhost ~]# .zip
 [root@localhost ~]# cd MySQL-python-
 [root@localhost MySQL-python-]# python setup.py install

2.3 安装报错

 sh: mysql_config: not found
 Traceback (most recent call last):
   File , in <module>
     metadata, options = get_config()
   File , in get_config
     libs = mysql_config("libs_r")
   File , in mysql_config
     raise EnvironmentError("%s not found" % (mysql_config.path,))
 EnvironmentError: mysql_config not found

安装libmysqlclient-dev

 [root@localhost MySQL-python-]# yum install libmysqlclient-dev

安装报错，并没有发现libmysqlclient-dev包

 [root@localhost requests-]# yum install libmysqlclient-dev
 Loaded plugins: fastestmirror
 Loading mirror speeds from cached hostfile
  * base: mirrors.sohu.com
  * extras: mirrors.sohu.com
  * updates: mirrors.sohu.com
 No package libmysqlclient-dev available.
 Error: Nothing to do
 [root@localhost requests-]# 

之所以会出现如下原因是系统没有找到mysql的依赖包,那么我们可以自己安装依赖，这儿依赖可以为mysql 也可以为mariadb

 [root@localhost MySQL-python-]# yum list all | grep mariadb | grep dev
 mariadb-devel.x86_64                        :-.el7             @base
 mariadb-embedded-devel.x86_64               :-.el7             @base
 mariadb-devel.i686                          :-.el7             base
 mariadb-embedded-devel.i686                 :-.el7             base
 [root@localhost MySQL-python-]# 

安装mariadb的dev包

 [root@localhost MySQL-python-]# yum install mariadb-devel mariadb-embedded-devel

再次安装MySQL-python-1.2.5

[root@localhost MySQL-python-1.2.5]# python setup.py install

再次报错

再次安装python-devel

 [root@localhost MySQL-python-]# yum install python-devel 

再次尝试

 [root@localhost MySQL-python-]# python setup.py install

检测是否安装OK

 [root@localhost MySQL-python-]# python

安装requests和MySQLdb到此结束
